Nest 构建在管道中失败：找不到本地构建时可以找到的模块

Question

在我的 NestJS 项目中，本地构建和运行是可行的，但是当在我的 Azure 管道中构建相同的代码时，它最近开始失败，因为在命令中找不到某些模块npm run build。当我在本地运行该命令时，没有任何问题并且可以正确构建。

有许多模块确实可以正确找到（或没有给出错误），那么为什么这些模块不能呢？您可以在 Imgur 上的此图像中找到我的文件布局的图像，并且相关文件可见。所有类都被声明为，export class ... {}并且大多数类也被导入到 AppModule 中，它们不会给出错误。

管道布置（相关部分）：

trigger:
  - master
  - dev

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: NodeTool@0
  displayName: 'Install Node 12'
  inputs:
    versionSpec: 12.0.0

- script: |
    npm install -g typescript
    npm install
    npm test
  displayName: 'run tests'

- script: |
    npm run build
  displayName: 'build dist folder'

它通过将构建代理更改为 macOs 来起作用。确实一定是区分大小写的地方出了问题。
